Thanks, Barb! You do such a great job of answering questions!
That is exactly right. It's just to make the soup smoother, but I agree, it helps thicken it up, too.
Glad you girls like it. I think this soup is divine! I also love the zucchini patties...you guys should try them with your little ones. If you peel the zucchini first, you can tell them it's potatoes and they will never guess, I promise!
